Sunman is an action platformer for the NES intended to be released in 1992. Gameplay is similar to Sunsoft's two Batmangames, with the primary difference being the ability to fly. Notably, unlike most unreleased games, it was never announced in gaming magazines, and its existence was unknown until a prototype was found and purchased by Lost Levels.[1]

Due to Sunsoft's earlier involvement with DC Comics character licenses, some people assumed that Sunman was originally intended to be a Superman game, but was changed later in development for unknown reasons. This was eventually confirmed in an interview with Sunman's director, Kenji Eno, and a prototype of the earlier Superman build was eventually discovered.
